Quantum dot conduction impacted by stoichiometry, not dangling bonds

Quantum dots are semiconducting, nanoscale clusters that show electronic characteristics distinct from both bulk-scale materials and single molecules. Their special characteristics make quantum dots attractive for a broad range of potential applications, including photovoltaics and nanoscale transistors. The size and shape of quantum dots impact electrical properties and can therefore be used to tune the… Continue reading Quantum dot conduction impacted by stoichiometry, not dangling bonds

Germanane: germanium&#39s answer to graphane

Soon after graphene sheets were being produced on a laboratory scale routinely, researchers began producing the hydrogenated version graphane (with a hydrogen atom on each carbon). This step is one of many approaches aimed at harnessing graphene’s powerful conductivity and is also being explored for hydrogen storage and other potential applications (more info in this… Continue reading Germanane: germanium&#39s answer to graphane

Drexler&#39s book tour extends to U.S. May6-9

Recently we pointed at a Forbe’s interview with Eric Drexler, in anticipation of his pending new book Radical Abundance. The book  has shipped, and Drexler’s tour schedule now includes a few stops on the coasts of the U.S: New York: May 6th Los Angeles: May 8th & 9th Seattle: May 9th Find exact times and… Continue reading Drexler&#39s book tour extends to U.S. May6-9

Silicene: silicon&#39s answer to graphene

**Updates: July 2014 — Research out of Argonne National Lab suggested that silicene may have never actually been successfully synthesized, rather that spectra indicate a mixture of silicon and silicon-substrate alloy; see article on Phys.org. August 2014 — Research out of Italy suggests that their spectra establish the presence of silicene though not in a… Continue reading Silicene: silicon&#39s answer to graphene

A framework to promote critical thinking about nanotechnology

Foresight’s Director of Education Miguel F. Aznar has proposed nine questions to promote critical thinking and contextual understanding of the issues related to nanotechnology to enable the general public and policy makers to make informed choices on subjects influenced by nanotechnology.

Superparamagnetism-explicated-for us

Even though the sound of it is something quite atrocious, superparamagnetism may become a familiar term in the context of nanoscale electronics and devices. Loosely speaking, superparamagnetism is a size-based phenomenon in which materials that are ferromagnetic on the macroscale — meaning predisposed toward strong magnetization at room temperature, such as iron and nickel —… Continue reading Superparamagnetism-explicated-for us

Atomically precise placement of dangling bonds on silicon surface

Nanotechnology researchers in London have used a scanning tunneling microscope to create atomically precise quantum states from dangling bonds on a silicon surface.

RNA-protein motor for unidirectional movement of DNA in nanomachinery

Revolution of DNA around a central channel, rather than rotation, is the method used by a viral molecular motor to package DNA. A structure facilitating bottom-up assembly may lead to roles in nanotechnology for these nanomotors.

Nanotechnology revolution: An interview with Eric Drexler

In anticipation of Eric Drexler’s new book, Forbes contributor Bruce Dorminey interviews him about the meaning of nanotechnology and its revolutionary prospects. Selected excerpt: … In what fields would APM cause the most pronounced economic disruption and the collapse of global supply chains to more local chains? The digital revolution had far-reaching effects on information… Continue reading Nanotechnology revolution: An interview with Eric Drexler

Re-engineering a junction to give a new twist to DNA nanotechnology

By forcing the geometry of the junctions upon which DNA nanotechnology depends, researchers have increased the collection of 2D and 3D structures that they can build to include wire frames and mesh structures.
